RFJA20 Air Jet Loom

The RFJA20 air jet loom is used to weave various natural, synthetic, rayon(manufactured) and blended fiber yarns into apparel, upholstery, and industrial fabrics.

Newly Added Functions Relative To RJFA10
1. The state-of-the-art electrical control system
2. Creative design of positive warp let-off mechanism
3. Breakthrough design of weft battening mechanism ensures the weft is consistently tensioned during weaving while there is little vibration generated by the beating-up tool.
4. The loom has as standard the double back beam which gives the warp its let-off motion.
5. Energy-efficient solenoid valve(electromagnetic valve)
6. Domestic pioneering weaving guidance system

1. The letter "L" represents the approximate length of a 800mm-diameter warp flange. Please directly contact us for other specifications.
2. When the warp flange diameter is 914mm or 1000mm, users need to raise the ground level or dig holes into the ground to hold the warp beam.

1. The weaving guidance system monitors the operating status of the loom and guides it to adopt the most suitable process for weaving quality fabric. Based on the air jet loom condition and weave specifications, the system can automatically set appropriate parameters. In addition, the automatic set-mark prevention setting system and weft insertion parameters setting system have been improved for more efficient and safer operation.
2. The state-of-the-art positive warp let-off mechanism is utilized to give improved tension to the warp and fit the specific request for high speed operation. This mechanism is usually fitted to the external of the loom wall panel so as to correct the installation eccentricity error.
3. The box-shaped wall panels on both sides of the air jet loom as well as the cross beam are made with high-rigidity materials, providing durability and vibration isolation during high speed weaving operation. The rocking shaft comes with middle bracings for support and the vibration absorber, providing for smooth, powerful beating up motion based on computer analysis. Vibration isolation means there is little vibration that can be felt by the loom during high speed weaving, thereby ensuring stable battening operation and quality fabrics.
4. The high rigidity loom frame, large diameter weaving gear shaft, and positive warp let-off drive shaft which is installed within the lubricating oil bath container, make for high speed weaving operation and are fit for the purpose of weaving high-density weaves.
5. For effective warp let-off motion, the loom adopts double back beam to keep a consistent, even tension across the warp and throughout the weaving process. This kind of beam can be used to weave fabrics with different densities and weights.
6. The new solenoid valve incorporates a recirculation chamber, which is highly responsive. As well as carrying the weft yarn across the warp sheet to the exact location, the air jet can do so via creating high speed, compressed air with stabilized air pressure. The integrated design of front beam and air slot is directly connected with the solenoid valve, which shortens the distance between the valve and nozzle thereby reducing air consumption.
